That would make a brilliant movie! She leaves the plane with her boyfriend and a couple of nervous passengers, taken to the airport concourse, where we witness the plane exploding upon take-off, killing all on board instantly.

Fast forward a year, woman and her boyfriend meet up with another woman who left the aeroplane before the disaster. They are sitting down for an outdoor meal, when unbenown to them, a United States Airforce F-35 at 20,000 feet has engine failure. The pilot bails out, his parachute fails as he's separated from his ejection chair. He accelerates earthbound, landing on the woman who made the fuss on the jet, killing them both instantly. His seat follows shortly, killing the woman's boyfriend by reducing him to an 8 inch tall pile of bones and blood. The woman screams, leaves the restaurant and runs down the middle of the road, arms waving, shouting and screaming. At that point, the F-35 completes its fall to Earth, hitting her at 540mph, leaving so little of her behind that even DNA matching fails to find a piece of her big enough to test. It could be called Final Destination, or something like that?

We subsequently find out that the other person who walked off the jet joined the Air Force, and was making his first solo flight, when engine failure forces him to eject at 20,000 feet...
